d79a4bc51b Make partial clone imply no-clone-bundle by default.
For large projects, clone bundle is useful because it provided a way to
efficiently transfer a large portion of git objects through CDN, without
needing to interact with git server. However, with partial clones, the
intention is to not download most of the objects, so the use of clone
bundles would defeat the space savings normally seen with partial
clones, as they are downloaded before the first fetch.

A new option, --clone-bundle is added to override this behavior.
Add a new repo.clonebundle variable which remembers the choice if
explicitly given from command line at repo init.

c0d1866b35 project/sync: move DeleteProject helper to Project
Since deleting a source checkout involves a good bit of internal
knowledge of .repo/, move the DeleteProject helper out of the sync
code and into the Project class itself.  This allows us to add git
worktree support to it so we can unlock/unlink project checkouts.

979d5bdc3e add experimental git worktree support
This provides initial support for using git worktrees internally
instead of our own ad-hoc symlink tree.  It's been lightly tested
which is why it's not currently exposed via --help.

When people opt-in to worktrees in an existing repo client checkout,
no projects are migrated.  Instead, only new projects will use the
worktree method.  This allows for limited testing/opting in without
having to completely blow things away or get a second checkout.

56ce3468b4 assume environment always accepts strings
Different Python & OS versions have different environ behavior wrt
accepted types & encoding.  Since we're migrating to be Python 3 only,
lets change our code to assume strings always work as that's what the
newer Python 3 does.  This will fail under Python 2 for some env vars,
mostly on Windows, but the effort of maintaining shim layers that can
handle these edge cases isn't worth it when we're dropping that code.

We leave the logic in the `repo` launcher for now as it is simple, and
we want it to be able to switch versions a bit longer than the rest of
the tree.

Here's the support table:
          |    *NIX      |         Windows           |
 Python 2 | ASCII string | str or bytes, not unicode |
 Python 3 | str or bytes | str only                  |

Windows uses strings natively in its environment all the time.  But it
doesn't allow unicode strings under Python 2, so we have to encode.

Python 2 on *NIX is funky in that it always lowers to ASCII, so we had
to manually encode to avoid errors regardless of unicode or str.

Python 3 on Windows & *NIX will accept strings.  *NIX will also accept
bytes but Windows will not.

5f2b045195 sync: change how we preserve objects in shared repos
Some automatic git operations will prune objects on us, and not just
the gc step.  Normally we don't care, but with shared projects, we
will have multiple git checkouts with refs that the others cannot
see, but with a shared object dir.  Any pruning of objects based on
refs in just one repo can easily break the others.

git-2.7.0 introduced a preciousObjects setting which tells git to
never prune objects for this exact scenario: there might be refs in
some location that git is unable to see.

cc960971f4 sync: add option to skip manifest update
The use case is any situation where your manifest does
not exist on server, but where you still want to do
full sync for the projects, without having your
workspace manifest switched to other branch or
forwarded to latest or similar.
This allows syncing to a historical manifest in git log,
that does not have a branch, as well as when integrating
something together that has not been pushed upstream yet.
Changes can also exist locally on a manifest that is
behind head, meaning not requiring rebase to latest.

Tested using:
  $ cd .repo/manifests/
  $ git checkout <any hash 1>
  $ <do local modifications>
  $ repo sync --no-manifest-update
  $ git checkout <any hash 2>
  $ repo sync --no-manifest-update

dff919493a sync: report list of failing git trees
When repo sync fails because some git trees are not in clean state and
as such can not be rebased automatically, it is a pain to figure out
which trees are the culprits.

With this patch the list of offending trees is printed when repo sync
reports checkout errors.

TEST=ran 'repo sync' and observed the proper list of directories show
     up after the final error message

The smart sync logic takes up about 45% of the overall Execute func
and is about 100 lines of code.  The only effect it has on the rest
of the code is to set the manifest_name variable.  Since this func
is already quite huge, split the smart sync logic out.

In commit d9e5cf0e ("sync: invert --force-broken with --fail-fast") the

ae6cb08ae5 split out cli validation from execution
A common pattern in our subcommands is to verify the arguments &
options before executing things.  For some subcommands, that check
stage is quite long which makes the execution function even bigger.
Lets split that logic out of the execute phase so it's easier to
manage these.

This is most noticeable in the sync subcommand whose Execute func
is quite large, and the option checking makes up ~15% of it.

The manifest command's Execute can be simplified significantly as
the optparse configuration always sets output_file to a string.

d9e5cf0ee7 sync: invert --force-broken with --fail-fast
People seem to not expect the sync process to halt immediately if an
error is encountered.  It's also basically guaranteed to leave their
tree in an incomplete state.  Lets invert the default behavior so we
attempt to sync (both fetch & checkout) all projects.  If an error is
hit, we still exit(1) and show it at the end.

If people want the sync to abort quickly, they can use the new option
--fail-fast.

e4e94d26ae init: add --submodules to sync manifest submodules
repo sync can sync submodules via the --fetch-submodules option.
However, if the manifest repo has submodules, those will not be synced.
Having submodules in the manifest repo -- while not commonly done -- can
be useful for inheriting a manifest from another project using <include>
and layering changes on top of it.  In this way, you can avoid having to
deal with merge conflicts between your own manifests and the other
project's manifests (for example, if you're managing an Android fork).

Add a --submodule option to init that automatically syncs the submodules
in the manifest repo whenever the manifest repo changes.

7f1ccfbb7b sync: Fix semaphore release bug that causes thread 'leaks'
When repo syncs a manifest that utilizes multiple branches
in the same project, then the sync will use an extra
thread for each "duplicate".  For example, if
the manifest includes the project "foo" and "bar"
twice, then "repo sync -jN" will fetch with N+2 threads.

This is caused by _FetchHelper() releasing the thread semaphore
object each time it's called, even though _FetchProjectList()
may call this function multiple times within the scope of a
single thread.

Fix by moving the thread semaphore release to
_FetchProjectList(), which is only called once per thread
instance.

4350791e0d On project cleanup, don't remove nested projects
When there are nested projects in a manifest, like on AOSP right now:

<project path="build" name="platform/build" />
<project path="build/blueprint" name="platform/build/blueprint" />
<project path="build/kati" name="platform/build/kati" />
<project path="build/soong" name="platform/build/soong" />

And the top "build" project is removed (or renamed to remove the
nesting), repo just wipes away everything under build/ and re-creates
the projects that are still there. But it only checks to see if the
build/ project is dirty, so if there are dirty files in a nested
project, they'll just be blown away, and a fresh worktree checked out.

Instead, behave similarly to how `git clean -dxf` behaves and preserve
any subdirectories that have git repositories in them. This isn't as
strict as git -- it does not check to see if the '.git' entry is a
readable gitdir, just whether an entry named '.git' exists.

If it encounters any errors removing files, we'll print them all out to
stderr and tell the user that we were unable to clean up the obsolete
project, that they should clean it up manually, then sync again.

Add repo start support for GITC checkouts. If the user is in
the GITC FS view, they can now run repo start to check out
the sources and create a new working branch.

When "repo start" is called on a GITC project, the revision
tag is set to an empty string and saved in a new tag:
old-revision. This tells the GITC filesystem to display the
local copy of the sources when being viewed. The local copy
is created by pulling the project sources and the new branch
is created based off the original project revision.

Updated main.py to setup each command's gitc_manifest when
appropriate.

Updated repo sync's logic to sync opened projects and
updating the GITC manifest file for the rest.

Don't emit a message when the netrc file doesn't exist or couldn't

Instead of trying to unpack the result of info.authenticators() and
catching the resulting TypeError when it's None, first store it to

Also remove an unused import.

bdb5271de3 GITC: Add repo sync support.
Add repo sync support for GITC checkouts. If the user is in the
GITC client directory they can still pull the sources as normal
if they pass in the --force-gitc argument. Otherwise the user
should call repo sync in the GITC view to update the user's
remote view. (This works because .repo in the GITC view will
link to .repo in the client config directory.)

Part of the support for this change is the refactoring of GITC
related code into gitc_utils.py.

abaa7f312f Add option to correct gitdir when syncing
In some cases, a user may wish to continue with a sync even though
it would require overwriting an existing git directory. This behavior
is not safe as a default because it could result in the loss of some
user data, but as an optional flag it allows the user more flexibility.

To support this, add a --force-sync flag to the sync command that will
attempt to overwrite the existing git dir if it is specified and the
existing git dir points to the wrong obj dir.

an option is explicitly given to repo sync.

8d20116038 repo: Support multiple branches for the same project.
It is often useful to be able to include the same project more than
once, but with different branches and placed in different paths in the
workspace. Add this feature.

This CL adds the concept of an object directory. The object directory
stores objects that can be shared amongst several working trees. For
newly synced repositories, we set up the git repo now to share its
objects with an object repo.

Each worktree for a given repo shares objects, but has an independent
set of references and branches. This ensures that repo only has to
update the objects once; however the references for each worktree are
updated separately. Storing the references separately is needed to
ensure that commits to a branch on one worktree will not change the
HEAD commits of the others.

One nice side effect of sharing objects between different worktrees is
that you can easily cherry-pick changes between the two worktrees
without needing to fetch them.

b2bd91c99b Represent git-submodule as nested projects, take 2
(Previous submission of this change broke Android buildbot due to
 incorrect regular expression for parsing git-config output.  During
 investigation, we also found that Android, which pulls Chromium, has a
 workaround for Chromium's submodules; its manifest includes Chromium's
 submodules.  This new change, in addition to fixing the regex, also
 take this type of workarounds into consideration; it adds a new
 attribute that makes repo not fetch submodules unless submodules have a
 project element defined in the manifest, or this attribute is
 overridden by a parent project element or by the default element.)

We need a representation of git-submodule in repo; otherwise repo will
not sync submodules, and leave workspace in a broken state.  Of course
this will not be a problem if all projects are owned by the owner of the
manifest file, who may simply choose not to use git-submodule in all
projects.  However, this is not possible in practice because manifest
file owner is unlikely to own all upstream projects.

As git submodules are simply git repositories, it is natural to treat
them as plain repo projects that live inside a repo project.  That is,
we could use recursively declared projects to denote the is-submodule
relation of git repositories.

The behavior of repo remains the same to projects that do not have a
sub-project within.  As for parent projects, repo fetches them and their
sub-projects as normal projects, and then checks out subprojects at the
commit specified in parent's commit object.  The sub-project is fetched
at a path relative to parent project's working directory; so the path
specified in manifest file should match that of .gitmodules file.

If a submodule is not registered in repo manifest, repo will derive its
properties from itself and its parent project, which might not always be
correct.  In such cases, the subproject is called a derived subproject.

To a user, a sub-project is merely a git-submodule; so all tips of
working with a git-submodule apply here, too.  For example, you should
not run `repo sync` in a parent repository if its submodule is dirty.

We can't just let this run wild with a high (or even low) -j, since
that would hose a system. Instead, limit the total number of threads
across all git gc subprocesses to the number of CPUs reported by the
multiprocessing module (available in Python 2.6 and above).

d947858325 sync: Keep a moving average of last fetch times
Try to more accurately estimate which projects take the longest to
sync by keeping an exponentially weighted moving average (a=0.5) of
fetch times, rather than just recording the last observation. This
should discount individual outliers (e.g. an unusually large project
update) and hopefully allow truly slow repos to bubble to the top.

67700e9b90 sync: Order projects according to last fetch time
Some projects may consistently take longer to fetch than others, for
example a more active project may have many more Gerrit changes than a
less active project, which take longer to transfer. Use a simple
heuristic based on the last fetch time to fetch slower projects first,
so we do not tend to spend the end of the sync fetching a small number
of outliers.

This algorithm is probably not optimal, and due to inter-run latency
variance and Python thread scheduling, we may not even have good
estimates of a project sync time.

69998b0c6f Represent git-submodule as nested projects
We need a representation of git-submodule in repo; otherwise repo will
not sync submodules, and leave workspace in a broken state.  Of course
this will not be a problem if all projects are owned by the owner of the
manifest file, who may simply choose not to use git-submodule in all
projects.  However, this is not possible in practice because manifest
file owner is unlikely to own all upstream projects.

As git submodules are simply git repositories, it is natural to treat
them as plain repo projects that live inside a repo project.  That is,
we could use recursively declared projects to denote the is-submodule
relation of git repositories.

The behavior of repo remains the same to projects that do not have a
sub-project within.  As for parent projects, repo fetches them and their
sub-projects as normal projects, and then checks out subprojects at the
commit specified in parent's commit object.  The sub-project is fetched
at a path relative to parent project's working directory; so the path
specified in manifest file should match that of .gitmodules file.

If a submodule is not registered in repo manifest, repo will derive its
properties from itself and its parent project, which might not always be
correct.  In such cases, the subproject is called a derived subproject.

To a user, a sub-project is merely a git-submodule; so all tips of
working with a git-submodule apply here, too.  For example, you should
not run `repo sync` in a parent repository if its submodule is dirty.

`R_HEADS` is imported twice, from both the git_refs and project
modules.

It is actually defined in git_refs, and in project it is imported
from there, so the import of `R_HEADS` from project in the sync
module is redundant.  Remove it.

`HEAD` is imported from project, but like `R_HEADS` it is actually

e2126652a3 Make "repo sync -j<count>" stop properly on Ctrl-C.
The threaded 'repo sync' implementation would very often freeze the
process when interrupted by the user with Ctrl-C. The only solution
being to kill -9 the process explicitly from another terminal.

The reason for this is best explained here:

http://snakesthatbite.blogspot.fr/2010/09/cpython-threading-interrupting.html

This patch makes all helper sync threads 'daemon', which allows the
process to terminate immediately on Ctrl-C.

Note that this will forcefully kill all threads in case of interruption; this
is generally a bad thing, but:

  1/ This is equivalent to calling kill -9 in another terminal, which
     is the _only_ thing that can currently stop the process.

  2/ There doesn't seem to be a way to tell the worker threads to
     gently stop when they are in a blocking operation anyway (even
     in the non-threaded case).

+ Do the same for "repo status -j<count>".

350cde4c4b Change repo sync to be more friendly when updating the tree
We now try to sync all projects that can be done safely first, before
we start rebasing user commits over the upstream.  This has the nice
effect of making the local tree as close to the upstream as possible
before the user has to start resolving merge conflicts, as that extra
information in other projects may aid in the conflict resolution.

Informational output is buffered and delayed until calculation for
all projects has been done, so that the user gets one concise list
of notice messages, rather than it interrupting the progress meter.

Fast-forward output is now prefixed with the project header, so the
user can see which project that update is taking place in, and make
some relation of the diffstat back to the project name.

Rebase output is now prefixed with the project header, so that if
the rebase fails, the user can see which project we were operating
on and can try to address the failure themselves.

Since rebase sits on a detached HEAD, we now look for an in-progress
rebase during sync, so we can alert the user that the given project
is in a state we cannot handle.

68194f42b0 Add a project progress meter to 'repo sync'
This way users can see how much is left during fetch.  Its
especially useful when most syncs are no-ops but there are
hundreds of repositories to poll.

b1562faee0 Add 'repo sync -l' to only do local operations
This permits usage of 'repo sync' while offline, as we bypass the
network based portions of the code and do only the local sync.

An example use case might be:

  repo sync -n  ; # while we have network
  ... some time later ...
  repo sync -l  ; # while without network, come up to date

3e768c9dc7 Add 'repo sync -d' to detach projects from their current topic
The -d flag moves the project back to a detached HEAD state,
matching what is listed in the manifest.  This can be useful to
set a client to something stable (or at least well-known), such as
before a sequence of 'repo download' commands are used to get some
changes for testing.

96fdcef9e3 Add 'repo sync -n' to only do the network transfer
This makes it easier to update all repositories, without actually
impacting the working directory, or learning about how to use
`repo forall -c 'git fetch $REPO_REMOTE' `.

2a1ccb2b0c Hide the internal sync --repo-upgraded flag from users
This is only meant to be passed through while repo upgrades itself
during a sync.  It should never be something a user invokes on
their own.

c95583bf4f Don't permit users to run repo status in a mirror client
If a client was created with "repo init --mirror" then there are
no working directories present, and no files checked out.  Using
a command like "repo status" in this context makes no sense, and
actually throws back a Pytyon traceback at the console when the
underlying commands fail out.

We now tag commands with the MirrorSafeCommand type if they are
able to be executed within a mirror directory safely.  Using a
command in a mirror which lacks this base class results in a
useful error letting you know the command isn't supported.

e284ad1d1a Add 'repo init --mirror' to download a complete forrest
The mirror option downloads a complete forrest (as described by the
manifest) and creates a replica of the remote repositories rather
than a client working directory.  This permits other clients to
sync off the mirror site.

A mirror can be positioned in a "DMZ", where the mirror executes
"repo sync" to obtain changes from the external upstream and
clients inside the protected zone operate off the mirror only,
and therefore do not require direct git:// access to the external
upstream repositories.

c9ef744c7b Install a default pre-auto-gc hook in all repositories
This hook is evaluated by `git gc --auto` to determine if it is a
good idea to execute a GC at this time, or defer it to some later
date.  When working on a laptop its a good idea to avoid GC if you
are on battery power as the extra CPU and disk IO would consume a
decent amount of the charge.

The hook is the standard sample hook from git.git contrib/hooks,
last modified in git.git by 84ed4c5d117d72f02cc918e413b9861a9d2846d7.
I added the GPLv2 header to the script to ensure the license notice
is clear, as it does not match repo's own APLv2 license.

We only update hooks during initial repository creation or on
a repo sync.  This way we don't incur huge overheads from the
hook stat operations during "repo status" or even the normal
"repo sync" cases.
